Arbitration & Mediation

Arbitration & Mediation

Since 2010, Katherine has served as Secretary or Assistant to the Tribunal in complex arbitrations chaired by Profs. Karl-Heinz Böckstiegel, William W. (Rusty) Park, and Klaus Peter Berger.  In this role, Katherine participated in international investment and commercial arbitration cases with amounts in controversy ranging from USD 5 million – USD 2.5 billion.  These cases involved a wide variety of industry areas, including international tourism, mining, oil & Gas, financial services, and joint ventures.

Katherine has assisted in international commercial cases involving state parties or entities that were close to the state, and in cases with purely commercial parties.  These cases were conducted under the rules of the International Chamber of Commerce (“ICC”), London Court of International Arbitration (“LCIA”), Dubai International Arbitration Centre (“DIAC”), the German Institution of Arbitration (“DIS”), or the Chinese European Arbitration Centre (“CEAC”). 

Katherine has served in ad hoc arbitrations using the United Nations Commission on International Trade Law (“UNCITRAL”) Rules and in investor-state arbitrations before the Stockholm Chamber of Commerce (“SCC”) and the International Centre for Settlement of Investment Disputes (“ICSID”).

Katherine lectures frequently on the subject of international arbitration.  She teaches International Commercial Arbitration at the University of Michigan Law School.



Prof. Dr. Karl-Heinz Böckstiegel (2018):  Starting from her time some eight years ago when she was at Cologne University, Katherine Simpson has helped me in many of the commercial and investment cases I chaired, as Secretary or Assistant to the Tribunal. She proved to be highly efficient in supporting my case management, researching sources, or providing narrative drafts for decisions the Tribunal had to make. Other members of the tribunal and the staff of various arbitration institutions appreciated her work and she was well respected by counsel of the parties. Obviously, over the years, she gained a large amount of experience and I have no doubt that, by now, she could efficiently and successfully serve as an arbitrator.

Prof. William W. (Rusty) Park (2018):  Dr. Simpson has been an excellent Tribunal Secretary and has now doubtlessly arrived at the point where she will provide fine service as an efficient and intelligent arbitrator.
